Application filed May 18,

To all whom it may concern Be it known that I. Huon G. MAowiL- LIAM. asubject of the King of Great Britain, and'resident of New Rochelle. inthe county of lvcstchcster and State of New York, have invented certainnew and useful Improvements in' Windows, of which the following is aspecification.

My invention relates to windows and has particular reference to a typewhich combines the advantages of a sliding sash for general purposes anda swinging member on each sash acting as a frame for the glass and bythe use of whichswinging feature the glass may be easily andreadily'cleaned both on the inside and the outside faces.

One of the objects of my invention is to provide window sashes of thetype described which are practical and of low cost and which can beeasily placed in any ordinary window frame and in such a manner thatrepairs may be easily made and outside screens, storm sashes. or blindsof full or half length may be permanently attached without interferingwith the operation of the window. I

A. further object is to produc-ean eilic ient combination of sasheswhich may each have a maximum of light giving space.

Another object is to provide means for making all joints around theswinging mem bers water and air tight as nearly as may be required.

Further objects are to provide proper joints between the sliding sasheswhen closed, to eliminate any rough projection on either surface of thesashes. and to providelocking means forsaid swinging members, lockingmeans for said sliding sashes when closed, and aligning means for saidsliding sashes when in registering position whereby the upper swingingmember may be swung through the lower sash when the lower swingingmember is open, and without danger of window breakage.

. Another. object is to provide supporting hinged means whereby thelower swinging member may swing clear of the upper swinging member whenthe latter is Other objects will become apparent as the descriptionproceeds.

My invention consists in such novel features of construction and arranement of parts as are hereinafter described and particularly pointed outin the claims .hereto appended, one practical embodiment of my "theusual manner the two sashes may opened.

invention being shown in the accompanying drawing in which- Fig. 1 showsthe general appearance of a window having my improved features.

Fig. 2 shows a part vertical side section through the window sashes.with the sashes and swinging members closed and locked.

Fig. 3 shows a similar part section with both sashes aligned inregistering position.

Fig. 4 is a detail view in section on line 4% of Fig. 3 showing wideopening of the upper swinging member. I

Fig. 5 is a detail of the sash construction.

Fig. 6 a detail of the flush member locking means. i

Fig. 7 is a top view of the sashes showing the beveled feature of theside edges of the swinging members.

Similar reference characters refer to similar parts throughout theseveral views.

I intend no limitations other than those of the claims A window framelof ordinary type is illustrated having fitted thereto my improvedsashes. top 2 and bottom 3 both of which slide in a well knownmanuerfithe weight cords of-thc sashes being shown for example as at 4passing over pulleys 5, only oneofwhich is shown. These sashes 2, 3, mayhave each an outside. sliding. and an inner swinging spectirely; theswinging member 9 of the upper sash being smaller than the smallest partof the opening provided in the lower sash for closure by swinging member10.

' Locking means are provided as for example a lock 6 on the lower sashframe 3 and a catch 7 on the lower rail of swinging member 9. A similarcatch. 7 may be swinging rigid frame member 9, 10, re-

placed on the upper portion of the sash-2 arranged to take into a\rcccss R in the window casing 1 when the By sliding sash 2 down andsash3 up brought into registering )osition (Figfli) in which position thecatch 7 of the upper sash may coact with the lock 6 of the lower sash tohold the two window sashes fixedly together. The swinging members 9,.10, may then be-swung inwardly one after the other as for cleaning ormending purposes. The swinging members are locked. in closed position asby flush locks 11 (Fig. 1 and Fig. 6). These locks may be: opened by theinsertion of a key and may be of an standard type but if used shouldbe'fiusii upper sash is closed.

frame flush with the beveled edge 13 against 10 which the beveled edge14 of the swinging frame abuts, the other art of the hinge be ing flushtherein. Sas es 2 and 3 are provided with Weatherstrip frames 15, 15 re--s actively, having each a periphery of the 15 s ape and bevel of thesides of the respective swinging member opening and having an anglecross section as shown. The frames 15, 15 are disposed between themembers 3 and 10 and 2 and 9.respectively when the .29 swingingtmembersare in normal position, 1 and eac frame ---provides a lip portionagainst which the respective .swingin r member tightly closes. Oneflange each Weatherstrip frame is sunk into the beveled 2 ed as 13 ofthe rails of its sash (Fig. 4),

an a channel or more is out in the face of each of the swinging members9, 10. as shown at 16, 16 (Fig. l) which inter-fits with the upturnedlip portion of the 39 weather strip 15, when the swinging 1 members areclosed.

* The upper swinging member 9 is supported by a hinge 19 (Fig. 4) sunkin both the sash and the member edges and the memher 9 ma be opened, atleast 90 degrees through t e lower sash opening when the member 10 isswung fully open.

In closed position of the sashes the swinging member'- 9 cannot beopened because it I 69 abuts the lower sliding sash 3 and in fact themember 9 can only be opened with both sashes registering.

With both sashes closed the lower sash cross bar interlocks at thecenter joint 21 with the upper sash cross bar (Fig. 2). in order toprovide for this joint and yet permit sliding the sashes together thelower sash top cross bar is wider than the bottom cross bar while theupper sash top cross bar is narrower than its bottom cross bar as shown.

Having thus described one embodiment of my invention what I desire toclaim is 1. In a window, an upper sliding sash frame having a centrallydisposed SWlIl ing member and a lower sliding sash frame aving acentrally disposed swinging member. means to lock both sashes togetherin registering position at any point and means whereby said upper sashswinging member may be swung inwardly through a centrally disposedopening in said lower sash frame, when the swinging member of said lowersash frame is open.

2. In a window, an upper slidin sash frame having a centrally d'l posedswinging n gmber and a lower sliding sash frame, having a centrally dsposed swinging member, means to lock said frames together in closedposition, additional means adapted to coact with part of the firstmentioned means to lock said frames together in registering position,and locking means for said swinging members, substantially as described.

Signed at New Rochelle, in the county of Westchestr and State of NewYork, this 18th day of March A. D. 1920.
